Description

FILTRE ANTIPOLLUTION AUTORÉGÉNÉRANT POUR MOTEURS
A EXPLOSION OU A COMBUSTION INTERNE FONCTIONNANT
AVEC TOUS TYPES DE CARBURANTS
La présente invention est constituée par un mélange approprié d'agrégats minéraux traités , combinés à un système filtrant lui permettant par combinaison l'élimination de plus de 90% d'émanation de gaz toxique
Différents moyens et techniques ont été utilisées dans ce but
Ces derniers temps ont été déposés des brevets concernant des pots d'échappement " antipolluants
Ces procédés mettent en place , des céramiques monolithes percées de trous pour le filtrage et l'évacuation des gaz d'échappement.SELF-GENERATING ANTI-POLLUTION FILTER FOR ENGINES
EXPLOSION OR INTERNAL COMBUSTION OPERATING
WITH ALL TYPES OF FUELS
The present invention consists of an appropriate mixture of treated mineral aggregates, combined with a filtering system allowing it by combination to eliminate more than 90% of toxic gas emanation.
Different means and techniques have been used for this purpose
In recent times, patents have been filed for "exhaust emissions"
These processes use monolithic ceramics with holes for filtering and removing exhaust gases.

Ces procédés de par même leur structure et leur rigidité d'utilisation ne permettent pas leur régénération. En effet les trous faits dans les filtres rigides s'encrassent rapidement et donc perdent de leur efficacité première
Les catalyseurs sont utilisés dans les < c pots catalytiques des automobiles afin de réaliser l'oxydation complète et rapide du combustible qui n'a pas été brûlé. II reste toujours du combustible non brûlé dans les gaz d'échappement qui sortent du moteur, il s'agit d'un mélange de monoxyde de carbone, d'hydrocarbure non brûlé et d'oxyde d'azote qu'on appelle de façon générale NOx. La pollution que peuvent provoquer ces substances est réduite si les composés carbonés sont oxydés en dioxyde de carbone et si NOx est réduit en azote . Cependant, bien qu'il soit facile de trouver un métal ou un oxyde métallique catalyseur pour accélérer ces réactions, il est très difficile de sélectionner les bons catalyseurs dans la pratique. Par exemple, un catalyseur qui réalise la réduction de NOx au delà de N2, notamment en NH3, n'est pas souhaitable, parce que l'ammoniac sera ensuite libéré dans l'atmosphère où il sera réoxydé en NOx. De plus, le catalyseur doit travailler même à des températures relativement basses, notamment celles que l'on a au démarrage des moteurs, car le problème d'émission des gaz est alors encore pire. C'est pour cette raison que des métaux bon marché tels que le cuivre sont moins utilisés que les métaux nobles et chers , tels que le platine : ces derniers sont actifs à basses températures Un problème supplémentaire apparaît à cause de la présence de soufre dans l'essence, car le catalyseur utilisé pour réduire les oxydes d'azote peut également catalyser l'oxydation de S02 en S03 ce qui transforme le véhicule en générateur d'acide sulfurique, c'est à dire une version mobile et urbaine du procédé de contact.These processes by their very structure and rigidity of use do not allow their regeneration. Indeed the holes made in the rigid filters quickly clog up and therefore lose their primary effectiveness
Catalysts are used in automobile catalytic converters to achieve complete and rapid oxidation of fuel that has not been burned. There is always unburned fuel in the exhaust gases leaving the engine, it is a mixture of carbon monoxide, unburned hydrocarbon and nitrogen oxide which is generally called NOx. The pollution that these substances can cause is reduced if the carbon compounds are oxidized to carbon dioxide and if NOx is reduced to nitrogen. However, although it is easy to find a metal or metal oxide catalyst to accelerate these reactions, it is very difficult to select the right catalysts in practice. For example, a catalyst that achieves the reduction of NOx beyond N2, especially NH3, is not desirable, because the ammonia will then be released into the atmosphere where it will be reoxidized to NOx. In addition, the catalyst must work even at relatively low temperatures, especially those that one has when starting the engines, because the problem of emission of gases is then even worse. It is for this reason that inexpensive metals such as copper are less used than the noble and expensive metals, such as platinum: the latter are active at low temperatures. An additional problem arises because of the presence of sulfur in gasoline, because the catalyst used to reduce nitrogen oxides can also catalyze the oxidation of S02 to S03 which transforms the vehicle into a sulfuric acid generator, i.e. a mobile and urban version of the contact process .

La présente invention est décrite ci-après en référence aux dessins annexés, soit la figure 1 suivant modèle. The present invention is described below with reference to the accompanying drawings, namely FIG. 1 according to model.
